r the rotation of the Worm wheel will also result movement of the driving unit will also result in tensioning of-the booster spring 36.-

. The hydraulic system is so timed that the s compression will commence substantially simultaneously withfthe' windingorieration' of the cables 44"and 45.- The; compression stroke in the cylinders 54 and 63 will in turn, push the lever 49 outward, as shown in Figure 2 of the draw I ings, against the tension of thespring 52, This.

operation Will, in turn, exert a pulling force on [by pins |9 riding on the cam 11. understoodthat. the cams are so arranged that 15 the'drive disc 24 and'the slidable clutch disc'r23 Tr:

from the worm wheel until thecables 44V and 45 have been wound to" their limit and theflever 49 pushed back to the limit of it 'tensioning stroke. As'soon as the clutchvhas become disengaged fromthe" worm wheel ifl the'ener yi tored in the'wou'nd cables 44 and 45 will become released and give a rotary impulse to"the drive'disc 24 and the; clutch disc"23'in' the opposite direction. .Byrea'son of the provision of the pawl'and ratchet device 43 and 42, this rotarym'oti'on' will rotate thef,:drive sl aft' 28 and the'fiy wheel 29.

"Thisrotary' motion may be taken cff by means Figure-6 also shows a modification, ofthe timing system; Instead of a master cylinder, an oil pump 69 is provided having a. circuit comprised of conduits 10 and H and bi-conduits 12 and 13 which lead .to a plurality of three-way valves 15. A separate three-way valve is pro-- vided for each drive unit to which it is connected by conduits 16, the three-way valves are actuated by the cams l which are driven by the motor in through thegearsyin the gear box ll an'dthe belt 18; The three-way valves are of conventional construction and may be actuated the "driving units will be actuated successively and that-the energy-storing stroke and the release stroke .of thej levers 49 are so timed that thdla'tter'will operate inthe manner heretofore described.
